Abstract:
Tailor-made blanks are sheet metal assemblies with different thicknesses and/or materials and/or surface coatings. A monolithic sheet can be machined to make the required thickness variations referred to as tailor machined blanks. Due to the thickness variation in tailor machined blanks, laser bending of these blanks is more complicated than that of monolithic plates. In this article, an artificial neural network (ANN) will be configured to predict the bending angle of laser formed tailor machined blanks. The input parameters of neural network are selected as the start point of scan path, laser irradiating method, laser beam diameter, laser output power and the number of radiation passes. The results show that a 5×8×1 trained neural network can predict the bending angle with acceptable accuracy. Comparison of the randomly selected tests with experimental results shows 1.1% error in the prediction of bending angle by trained artificial neural network.
